The oldest female elephant in South Korea passed away Tuesday at a zoo in Gwacheon, Gyeonggi Province, at the age of 59, zoo officials said Thursday. The female elephant, named Sakura, had suffered from deteriorating health since November last year, primarily caused by ascites and subcutaneous edema. Born in February 1965 in Thailand, she was in her 90s in human years. Sakura spent her early years as a circus perform.
